chkdsk

Chkdsk, short for "check disk," is a command line tool available in Windows operating systems. It is used to analyze, diagnose, and repair issues with the file system and disk integrity.

Chkdsk scans the file system to detect any physical and logical errors, such as bad sectors, lost clusters, and cross-linked files. It can be utilized for both local hard drives as well as external storage devices.

When run with the "/f" parameter, chkdsk automatically fixes errors encountered during the scan, making it a valuable tool for troubleshooting various disk-related problems.

Additionally, it can also be used with the "/r" parameter to detect and recover information from damaged sectors on the disk. This can help recover data and prevent further corruption or loss.

The chkdsk command can be executed from the Command Prompt or through the Windows Recovery Environment for more advanced disk repair options.

It provides a detailed report after completion, which displays the number of files, folders, and disk space scanned, as well as any errors found and repaired during the process.

Overall, chkdsk is an essential command line tool that helps maintain the health and integrity of the file system and is often used to troubleshoot disk issues in Windows.
